What is the square root of 99 to the nearest tenth? <\/p>\n\n\n\n
A. 9.9 <\/p>\n\n\n\n
B. 10.9 <\/p>\n\n\n\n
C. 11.9 <\/p>\n\n\n\n
D. 12.9<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n To find the square root of 99 to the nearest tenth, we first need to determine the square root of 99 using a calculator or estimation.<\/p>\n\n\n\n The square root of 99 is approximately 9.949874. When rounded to the nearest tenth, this gives us 9.9.<\/p>\n\n\n\n Now let’s understand why this happens. The square root of a number is the value that, when multiplied by itself, equals the original number. In the case of 99, we know that 9 multiplied by 9 is 81, and 10 multiplied by 10 is 100. So, the square root of 99 must be between 9 and 10. More specifically, it is closer to 10 than to 9, as the square of 9.9 is 98.01, which is much closer to 99 than the square of 9 is (which is 81).<\/p>\n\n\n\n To find the square root of 99 more precisely, we can use a calculator, which gives us the value of 9.949874. When rounding this to the nearest tenth, we look at the digit in the hundredths place. If it is 5 or higher, we round up. Since the hundredths place in this case is 4, we round down to 9.9.<\/p>\n\n\n\n Thus, the correct answer is A. 9.9<\/strong>.<\/p>\n\n\n\n This kind of estimation is helpful when you don’t have a calculator and need to quickly approximate the square root of a number. The key is understanding the proximity of the number to known perfect squares, in this case, 81 (9\u00b2) and 100 (10\u00b2).<\/p>\n","protected":false},"excerpt":{"rendered":" What is the square root of 99 to the nearest tenth?
